Wet Abrasion Washability Scrub Tester ASTM D3450 Sponge

ASTM D3450 Wet Abrasion and Washability - Scrub Tester with Sponge Brushes

SKU: CA-12500

Abrasion or Wear Resistance of a product being washed is a very important quality measure for both paints and coatings. How can we measure this? It can be accomplished by having a system that duplicates hand washing with a sponge, nylon brush, abrasive pad, or a natural bristle brush for a designated number of repetitive cycles. After the test is complete, compare the sample originally to the one after the abrasion test. You can compare samples by using a Gloss Meter for dullness,  or you can measure the weight difference before and after, or by measuring the color difference between the original sample versus the washed sample.

All Four MIZA models are used to test the abrasion, scrub, and washability performance of many types of materials. The MIZA models perform abrasion scrub washability tests in wet or dry conditions. To see all four models scroll to the bottom of this page.

The MIZA Scrub Washability Testers come with a large touch screen for quick and simple control of cycles, flow, etc., and are widely used in water-based coating applications for wear resistance.

The ASTM D3450 Wet Abrasion and Washability - Scrub Tester with Sponge Brushes (MIZA CA-12500) comes with two 750g weight brushes that are used to test the abrasion, scrub, and washability performance of your products, usually a coating like paint as per ASTM D3450. This instrument is built tough to last many years. This very versatile instrument allows you to perform the tests under either dry conditions or wet conditions through the LCD display. A peristaltic built-in pump and a water solution bottle and tubing are all included in this package. As an added benefit we also include two spare brushes for even longer satisfaction. All our equipment comes with an extended 3-year warranty from us.
